Abstract (en)

[origin: WO2019069023A1] The invention concerns a component (10) comprising: a substrate (20) of which at least one part adjacent to a surface (S) of the substrate is made from a material comprising silicon; a bonding sublayer (30) situated on the surface (S) of the substrate and comprising silicon, an environmental barrier (40) that comprises an outer layer (42) made from ceramic covering the bonding sublayer (30), characterised in that said environmental barrier (40) additionally comprises a self-healing inner layer (41) situated between the bonding sublayer (30) and the outer layer (42), said inner layer (41) comprising a matrix in which silica-forming particles are dispersed, these particles being capable of generating a crack-healing phase in the matrix in the presence of oxygen.
